L'invention concerne un procédé de pilotage d'affichage, un panneau d'affichage et son procédé de fabrication, et un dispositif d'affichage. Le procédé de pilotage d'affichage comprend les étapes suivantes : utiliser au moins deux circuits de pilotage de données pour piloter une région d'affichage d'un panneau d'affichage (101) ; chacun des circuits de pilotage de données pilote une partie de la région d'affichage du panneau d'affichage (102) ; et rassembler les régions d'affichage pilotées par différents circuits de pilotage de données en la région d'affichage entière (103). Dans le procédé de pilotage d'affichage, une pluralité de circuits de pilotage de données sont utilisés pour réaliser un pilotage d'affichage sur une région d'affichage d'un panneau d'affichage. De cette manière, une région d'affichage pilotée par chacun des circuits de pilotage de données est relativement petite, et une différence entre des distances du circuit de pilotage de données à différents sous-pixels dans la région d'affichage pilotée est relativement petite, permettant ainsi de réduire la différence de luminance provoquée par cela.
